Messaging on the HTC Rezound is straightforward, with SMS messages presented in a conversation view as if they're written on little slips of paper.
The People app's consolidated contact listing makes it easy to stay in touch, no matter how you interact with a particular contact.
When it comes to email, the Rezound offers a few different options out of the box. There's a dedicated Gmail app, which can handle multiple accounts, or there's a Mail app, which can tap into everything from Verizon.net accounts to Microsoft Exchange, AOL, Yahoo, Gmail (again!) and any generic IMAP or POP3 accounts.
